basic.texi claims

`M-='
     Display the number of lines in the current region
     (`count-lines-region').  *Note Mark::, for information about the
     region.

(taking the info version), however, at least two emacs modes (dired and
calendar) overrides this key binding. I think these exceptions ought to be
documented here. 

I'm often trying to count lines in a region in dired and
I very rarely use dired-backup-diff as I use version control and that
function doesn't use vc and therefore I get an error on M-=. 

Could dired-backup-diff, if it doesn't find a backup file, test for
region-active-p and if t invoke count-lines-region and only otherwise
signal an error?

Thanks for the suggestion.  Now this is fixed so that `M-=' is not bound to
dired-backup-diff, and the global `count-words-region' is in effect in Dired.
